Question

I'm new to EMC xDB and I'm trying to understand how it works. I have read some of the documentation, but can't find the answer for my question.

What is the best method for an XML content search?

I can make a xQuery search/operation, but I can't figure out how I make an XML content search?

Let's assume I want to make a xQuery in dir "/test" and want to search if any XML files contains the number "102548458"

答案取决于您的意思＆＃34; XML内容搜索＆＃34; - 全文搜索的精确值比较？ xDB支持两者。

对于精确值匹配（＆＃34;返回/test库中/foo/bar＆＃34;元素等于102548458）的所有XML文档，您可以使用简单的XQuery如下：

for $x in doc('/test')
where $x/foo/bar = 102548458
return $x

要执行全文搜索（＆＃34;返回/test库中/foo/bar＆＃34;包含文本102548458）的所有XML文档，您可以使用以下XQuery Full Text查询：

for $x in doc('/test')
where $x/foo/bar contains text '102548458'
return $x
